Part IV. Networking

Connecting to a
Network

The LFS book covers setting up networking by connecting to a LAN with
a static IP address. There are other methods used to obtain an IP
address and connect to a LAN and other networks (such as the
Internet). The most popular methods (DHCP and PPP) are covered in
this chapter.

DHCP stands for Dynamic Host Configuration Protocol. It is a protocol
used by many sites to automatically provide information such as IP
addresses, subnet masks and routing information to computers. If your
network uses DHCP, you will need a DHCP client in order to connect to
it.

PPP stands for Point-to-Point Protocol. It is a data link protocol
commonly used for establishing authenticated IP connections over a
phone line with a modem, or over radio waves with a cellular phone.
There is also a variant (PPPoE) that works over Ethernet and is used
by cable providers to authenticate the Internet connections.
